那 Color 是要畫焦點矩形的物件背景顏色。

範例

以下程式碼範例示範使用該 DrawFocusRectangle 方法與屬性 Control.Handle 。 要執行這個範例，請將以下程式碼貼上表單。 在表單中新增兩個名為 Button1 Button2 的按鈕，並確保所有事件都連接到它們的事件處理器。

// This method draws a focus rectangle on Button2 using the 
// handle and client rectangle of Button2.
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   ControlPaint::DrawFocusRectangle( Graphics::FromHwnd( Button2->Handle ), Button2->ClientRectangle );
}

// This method draws a focus rectangle on Button2 using the 
// handle and client rectangle of Button2.
private void Button1_Click(System.Object sender, System.EventArgs e)
{
    ControlPaint.DrawFocusRectangle(Graphics.FromHwnd(Button2.Handle), 
        Button2.ClientRectangle);
}

' This method draws a focus rectangle on Button2 using the 
' handle and client rectangle of Button2.
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click
    ControlPaint.DrawFocusRectangle(Graphics.FromHwnd(Button2.Handle), _
    Button2.ClientRectangle)
End Sub
